I changed the subject line to make this a bit easier to find in
future, if someone is looking on the archives - and wow, it works
beautifully-- what a great enhansonment! ;^)

good call, Angel -- yes, this is a Jmol-user issue, not a developer

Michael, if you Google
apple resize
you will get a number of solutions for automatically resizing an
applet
-- Sounds like Angel has one.
See for example
http://blog.taragana.com/index.php/archive/resizing-applets-
dynamically-within-browser-frames/
It uses something like this (MSIE only here). One trick might be
that on
load the applet may not be fully initiallized. My quick an dirty
solution based on that JavaScript code is at
http://www.stolaf.edu/academics/chemapps/jmol/docs/examples-11/
resize.htm
Note that I issue
zoomLarge = false
at the beginning of my script -- That's to ensure that as the applet
resizes the molecule stays within the window.
There's also a hack in there because Jmol.js doesn't support
proportional size windows. [We should fix that, Angel. Perhaps just
allowing: jmolApplet(["50%","50%"]) or jmolApplet("50%") -- I think
it's
one line of code.]
There is no issue of "flood Jmol with refreshes". Jmol just ignores a
resize if it is the same dimensions as it already has.
And if it is currently in the process of refreshing, it ignores a
refresh request. So that's not an issue. Especially in a
case like this where you know for a fact the browser is MSIE
because it
is a component of your Visual Basic program.
Again, window resizing is standard procedure with the application
-- the
Jmol end of things has been capable of this for a long time. This is
just the first time anyone has thought about it in terms of the
applet.

thanks for your comments on the applet size.
In my case Visual Basic (VB) is providing the Web-window and Bob's
script is providing communication - via the hard disk. I added an
explicit VB button (command) to reset the applet to a new size,
based on
the current window size; this works, but of course resets the
molecule.
It was not reasonable to do it during resizing, since the round
trip to
the disk is too slow.
I did try to paste in the suggestion by Angel H.:
<script type="text/javascript">
function resize(n)
{
document.getElementById("jmolApplet0").width = n
document.getElementById("jmolApplet0").height = n
}
function resizeCSS(n)
{
document.getElementById("jmolApplet0").style.width = n+"px"
document.getElementById("jmolApplet0").style.height = n+"px"
}
</script>
but I got errors. Maybe Bob can tell me what exact form I need
within
the current script he setup.
Overall we need an applet size that follows a percentage of the
Web-window (without having to pass external messages via the disk).
hopefully I can now respond via the Jmol users group.
thanks again,
Michael, if you just need an applet that is sized a percent of the
web page window, that can be done easily (I can send you my
JavaScript code that works). The tricky part is to have the applet
resize when the browser is resized. As pointed out by Miguel, this
probably involves too many resize events and can choke Jmol, or the
browser.
But a per-request resize should also be easy to have.
Please, advise
